• Advantages
• As a low output voltage, highly efficient
  solution, the GH Series addresses the ongoing
  need to reduce the overall size and weight of the
  system together with the increasing requirements
  of FPGA and other digital circuitries for
  increased bandwidth and data processing speed of
  spacecraft electronics
• The GH Series was developed using a proven
  space-level design methodology that includes
  selection of established reliable components and
  fully de-rated to the requirements of
  MIL-STD-1547. The devices feature magnetically
  coupled feedback to insure robust operation under
  the intended radiation environments.
• The output models range from 1.0V to 5.0V with
  current rating of up to 20A and high efficiency
  up to 87. Output is adjustable with an external
  resistor for a precise output voltage setting
  with the adjustment range of 10 of the rated
  output voltage.

• Features
• 18 to 40 volt input range
• Total Ionization Dose gt 100K Rad (Si)
• SEE LET (Heavy Ions) gt 82 MeV.cm2/mg
• Internal EMI filter, complying with most major
  satellite power buses
• Low weight, 110 grams
• Magnetically coupled feedback
• Single output models include 1.0, 1.5, 1.8, 2.5
  3.3, 5V
• High efficiency to 87
• Adjustable output voltage
